back home. Today, how do you change the way you think? How do you change the way you think from the robin I first saw countless years ago. With pigtails. Yes. I -- and I know you will find this hard to believe, especially in the line of work that we are in. I just think about now. I just think about this moment. So, that's how I changed the way I think. I don't think about anything else, about, right this moment. I'm talking to a dear, old friend. If this has taught me anything, it's that I don't care who you are, where you are, what your circumstances. There is a finite amount of time that we all have to do whatever it is that we're meant to do. And nowhere is it written that we should not be happy, that you get extra bonus points at the end because you -- you know, you trudged along and you did what you thought you should do. I want to be happy. Now, are there days -- this is a good day. And there are some days you have that it kind of creeps in. But I don't -- do you have something you do when it does? Do you have something -- do you have something you do that everybody in their lives will keep the clothes in if the door is open. They look at you thinking, if she can make it a good day, maybe I can, too. What do I do? I breathe. Left foot, right foot, breathe. Left foot, right foot, breathe. What do you see when you look in your eyes, your own eyes nong? You know what? I see a strong woman. I know people have said that about me. But we all know our own insecurities. And we all know how we all really feel about ourselves. There is something freeing. There's something liberating about not being afraid. Being afraid but still doing it because if we wait until there's no fear, we're going to be waiting a long time on the sidelines. If I can go through the year that I had and still be standing, wow. I'm not as afraid of what can come next.
